; cperl-mode: bugfix / rework fontification of here-docs
* lisp/progmodes/cperl-mode.el (cperl-mode): Use
`cperl-font-lock-syntactic-face-function'.
(cperl-commentify): Add a docstring, eliminate unused formal
parameter `noface'.
(cperl-is-here-doc-p): New function to detect whether "<<" starts
a here-document, factored out from `cperl-find-pods-heres'.
(cperl-here-doc-functions): New variable: List of functions which
allow here-documents as parameters, for use in
`cperl-is-here-doc-p'.
(cperl-process-here-doc): New function, factored out from
`cperl-find-pods-heres'. Fixed to keep correct fontification
after non-interactive (elisp) changes (Bug#14343, Bug#28962).
(cperl-find-pods-heres): Extend the doc-string to describe all
parameters. Don't remove text properties in recursive calls on
the same line. Call `cperl-process-here-doc' when appropriate.
(cperl-font-lock-syntactic-face-function): New function to
highlight c-style comments as here-documents (adapted from
perl-mode.el).

`cperl-is-here-doc-p'.

`cperl-is-here-doc-p', testing constructs which start with "<<"
but are no here-documents.
(cperl-test-here-doc-missing-end): New test to verify correct
detection of a missing here-document delimiter.
(cperl-test-bug-14343): New test to verify that inserting text
into a here-document with elisp does not break fontification.
* doc/lispref/frames.texi (Finding All Frames): Clarify what it
means to "consider".
* src/frame.c (Fnext_frame): Rewrite doc string to say what the
parameters actually mean (bug#13339).

* doc/emacs/files.texi (Auto Save Files): Document it.
* lisp/cus-start.el (standard): Add customize form.
